To convert 2-column vectors to 5 column vectors for comparison of grouped data

target=half_decay; grp=1:5; grouplength=ones(1,5); for i=1:5 grouplength(i)=length(find(target(:,2)==i)); end largest_groupnumber=max(grouplength); finalmatrix=NaN(largest_groupnumber,5); for ii=1:5 for iii=1:grouplength(ii) aa=target(find(target(:,2)==ii)); finalmatrix(iii,ii)=aa(iii); end end
